Exploited Entry Points: How Ticketing Systems Like Zendesk Become Breach Vectors

From small startups to global enterprises—whether legitimate companies or less-than-legitimate operations—growing customer demands, operational needs, and complex workflows have pushed many to adopt ticketing or triage solutions like Zendesk, Freshdesk, Zoho, Jira, and others. These platforms help manage internal and external queries from staff, partners, customers, and suppliers.

While these systems enhance organizational efficiency by centralizing communication and support, they also represent a growing cybersecurity blind spot. As the infostealer ecosystem expands rapidly, attackers increasingly exploit ticketing systems as vulnerable entry points into companies. Protecting this overlooked segment of the supply chain has never been more critical.

In this article, we examine Zendesk, a ticketing solution used by over 100,000 companies, and analyze its compromise footprint using data sourced from Infostealers.info—a specialized OSINT platform that aggregates credential logs, metadata, and infection patterns linked to infostealer malware. It enables investigators and cybersecurity teams to trace compromised identities, map exposure paths, and uncover broader threat actor infrastructure.

Conclusion: Ticketing Systems Are the Forgotten Front Line

Zendesk and similar platforms play a vital role in streamlining enterprise support.
